## What is it?

Comfy Catapult is a library for scheduling and running ComfyUI workflows from a
Python program, via the existing API endpoint. ComfyUI typically works by
hosting this API endpoint for its user interface.

This makes it easier for you to make workflows via the UI, and then use it from
a program.

## Getting Started

### Exporting workflows in the API json format

In ComfyUI web interface:

1. Open settings (gear box in the corner).
2. Enable the ability to export in the API format, `Enable Dev mode Options`.
3. Click new menu item `Save (API format)`.

![ComfyUI API format export instructions](assets/comfy-export-instructions.png)

### Example workflow: Prepare ComfyUI

**If you don't want to try the example workflow, you can skip this section.**

You need to get `sd_xl_turbo_1.0_fp16.safetensors` into the ComfyUI model
directory.

Hugging Face page:
[huggingface.co/stabilityai/sdxl-turbo/blob/main/sd_xl_turbo_1.0_fp16.safetensors](https://huggingface.co/stabilityai/sdxl-turbo/blob/main/sd_xl_turbo_1.0_fp16.safetensors).

Direct download link:
[huggingface.co/stabilityai/sdxl-turbo/resolve/main/sd_xl_turbo_1.0_fp16.safetensors](huggingface.co/stabilityai/sdxl-turbo/resolve/main/sd_xl_turbo_1.0_fp16.safetensors).

### Download the example workflow, and export it in the API format

**This is optional, you can use the example workflow in `test_data/` instead and
skip this step.**

```bash
# Download the workflow:
wget https://github.com/comfyanonymous/ComfyUI_examples/raw/master/sdturbo/sdxlturbo_example.png

# 1. Open the Workflow in ComfyUI and export it. AFAIK there isn't a nice way
# to automated this right now.
#
# 2, Save to `./sdxlturbo_example_api.json`.
#
# Or just use `test_data/sdxlturbo_example_api.json`.
```

### Install as a library and run the examples

```bash
# Inside your environment:
pip install comfy-catapult



# If you set this environment variable, you don't have to specify it as an
# argument.
export COMFY_API_URL=http://127.0.0.1:8188
# Note, in WSL2 you may have to use the IP of the host to connect to ComfyUI.


python -m comfy_catapult.examples.sdxlturbo_example_catapulter \
  --api_workflow_json_path "$PWD/sdxlturbo_example_api.json" \
  --tmp_path "$PWD/.deleteme/tmp/" \
  --output_path "$PWD/.deleteme/output.png" \
  --positive_prompt "amazing cloudscape, towering clouds, thunderstorm, awe" \
  --negative_prompt "dull, blurry, nsfw"

# Optional if you don't want to set the environment variable:
#   --comfy_api_url "..."

# Done! Now $PWD/.deleteme/output.png should contain the output image.

# Some other examples:
python -m comfy_catapult.examples.add_a_node
python -m comfy_catapult.examples.using_pydantic



```

- Examine
  [`examples/sdxlturbo_example_catapulter.py`](examples/sdxlturbo_example_catapulter.py)
  to see how to use the main `ComfyCatapult` library.
- Examine
  [`test_data/sdxlturbo_example_api.json`](test_data/sdxlturbo_example_api.json)
  to see the API format. This will be necessary in order to programmatically set
  the proper inputs for the workflow.
  - (Optional) See [`examples/using_pydantic.py`](examples/using_pydantic.py)
    for how to parse the API format into the Pydantic models schema for easier
    navigation.
  - (Optional) See [`examples/add_a_node.py`](examples/add_a_node.py) for how to
    add a new node to a workflow. This is useful when you need to add nodes at
    runtime (such as adding a bunch of LoadImage nodes).
- See [`comfy_catapult/catapult_base.py`](comfy_catapult/catapult_base.py) for
  the main library interface.
- (Optional) See [`comfy_catapult/catapult.py`](comfy_catapult/catapult_base.py)
  for the main library implementation.
- (Optional) See
  [`comfy_catapult/api_client_base.py`](comfy_catapult/api_client_base.py) for
  the direct ComfyUI API endpoint client library interface; you don't need to
  use this usually.
- (Optional) For those who want to do use the raw API themselves and learn how
  it works: Examine
  [`comfy_catapult/api_client.py`](comfy_catapult/api_client.py) to see the API
  client implementation if you want to directly interface with ComfyUI endpoints
  yourself.
  - (Optional) Also see
    [ComfyUI/server.py](https://github.com/comfyanonymous/ComfyUI/blob/977eda19a6471fbff253dc92c3c2f1a4a67b1793/server.py#L99)
    (pinned to a specific commit) for the server `@routes` endpoint
    implementations.

### Development; install dependencies and run the examples

This is if you are intending on contributing or altering the library itself.

```bash

git clone https://github.com/realazthat/comfy-catapult.git
cd comfy-catapult
pip install -r requirements.txt


# Run the example workflow:
PYTHONPATH=$PYTHONPATH:$PWD python examples/sdxlturbo_example_catapulter.py \
  --api_workflow_json_path "$PWD/sdxlturbo_example_api.json"
  --tmp_path "$PWD/.deleteme/tmp/" \
  --output_path "$PWD/.deleteme/output.png" \
  --positive_prompt "amazing cloudscape, towering clouds, thunderstorm, awe" \
  --negative_prompt "dull, blurry, nsfw"


```

### Parsing the API format into the Pydantic models schema for easier navigation

From [`{{ path('examples/using_pydantic.py') }}`](examples/using_pydantic.py):

`{{ snippet('examples/using_pydantic.py', start='SNIPPETSTART', end='SNIPPETEND', backtickify='py') }}`

### Adding a new node to a workflow

From [`{{ path('examples/add_a_node.py') }}`](examples/add_a_node.py):

`{{ snippet('examples/add_a_node.py', start='# SNIPPETSTART', end='# SNIPPETEND', backtickify='py') }}`

## Requirements

- Python 3.10+
- ComfyUI server with API endpoint enabled.

### Known to work on

- **Python 3.10.0**, WSL2/Windows11, Ubuntu 22.04.2 LTS
- **Python 3.10.0**, Ubuntu 22.04

## Limitations

- ETA estimator isn't working

## TODO

- [ ] Helpers should support remote/cloud storage for ComfyUI input/output/model
      directories (Currently only supports local paths).
- [ ] ETA Estimator.
- [ ] Make sure the schema can parse the formats even if the format adds new
      fields.

## Contributions

### Development environment: Linux-like

- For running `pre.sh` (Linux-like environment).
  - Requires `pyenv`, or an exact matching version of python as in
    [`{{path('.python-version')}}`](./.python-version).
  - `jq`, ([installation](https://jqlang.github.io/jq/)) required for
    [yq](https://github.com/kislyuk/yq), which is itself required for our
    `{{path('README.md')}}` generation, which uses `tomlq` (from the
    [yq](https://github.com/kislyuk/yq) package) to include version strings from
    `{{path('pyproject.toml')}}`.
  - `bash`, `grep`, `awk`, `sed` `xxd`, `git`, `xxhash` (for tests/workflows).
  - Requires nodejs (for act).
  - Requires Go (to run act).
  - docker (for act).

### Commit Process

1. (Optionally) Fork the `develop` branch.
2. Stage your files: `git add path/to/file.py`.
3. `bash scripts/pre.sh`, this will format, lint, and test the code.
4. `git status` check if anything changed (generated `{{path('README.md')}}` for
   example), if so, `git add` the changes, and go back to the previous step.
5. `git commit -m "..."`.
6. Make a PR to `develop` (or push to develop if you have the rights).

## Release Process

These instructions are for maintainers of the project.

1. `develop` branch: Run `bash {{path('scripts/pre.sh')}}` to ensure everything
   is in order.
2. `develop` branch: Bump the version in `{{path('pyproject.toml')}}`, following
   semantic versioning principles. Also modify the `last_unstable_release` and
   `last_stable_release` in the `[tool.comfy-catapult-project-metadata]` table
   as appropriate.
3. `develop` branch: Commit these changes with a message like "Prepare release
   X.Y.Z". (See the contributions section [above](#commit-process)).
4. `master` branch: Merge the `develop` branch into the `master` branch:
   `git checkout master && git merge develop --no-ff`.
5. `master` branch: Tag the release: Create a git tag for the release with
   `git tag -a vX.Y.Z -m "Version X.Y.Z"`.
6. Publish to PyPI: Publish the release to PyPI with
   `bash scripts/deploy-to-pypi.sh`.
7. Push to GitHub: Push the commit and tags to GitHub with `git push` and
   `git push --tags`.
8. `git checkout develop && git merge master` The `--no-ff` option adds a commit
   to the master branch for the merge, so refork the develop branch from the
   master branch.
